Which statement regarding under dispenser containment is false?

Under dispenser containment systems are designed to prevent the release of hazardous substances, such as fuel, into the environment. The statement indicating that a sensor in the turbine sump waives monitoring is incorrect because it implies that having a sensor negates the need for a more comprehensive leak detection system. In reality, while sensors can play a role in leak detection, they are not a substitute for an overall continuous monitoring system that ensures the containment system operates effectively.

In many regulatory frameworks, a continuous monitoring system is mandated for under dispenser containment to provide real-time detection of leaks. This real-time monitoring capability is crucial for quickly identifying issues before they escalate into significant environmental concerns. Additionally, the requirement for periodic testing of secondary containment systems ensures that these systems remain functional over time and comply with regulatory standards, reinforcing the importance of comprehensive monitoring rather than relying solely on localized sensors.

Overall, the necessity for continuous monitoring and regular testing underscores the importance of proactive environmental management in facilities with underground storage tanks.
